The Moderately halobacterium-SL21 was isolated from the brine sludge of a saltern,at Pulandian city of Dalian in China and identified with the morphologic characteristics and molecular biological method.With 16S rDNA technology,the phylogenetic tree was established.The strain was gram negative bacteria and cellular shapes of it was rod-shaped.The optimal growth NaCl concentration was 10%.A phylogenetic tree was constructed by comparing with the published 16S rDNA sequences of the relative bacteria species.A...
